Thrithala is 75 km from Palakkad situated along the banks of Bharathapuzha river, Thrithala is famed for its Shiva temple. Kattilmadom temple on the Pattambi-Guruvayoor road has archaeological importance. The small granite structure, a testimony of Buddhist influence, built probably during the 9th or 10th century. The ruins of a large fort with a deep moat hewn from laterite and the Kattil Madom temple, a domed structure of granite slabs on the Pattambi - Guruvayoor road are the prime attractions.
The temple probably marks the transition from the Chola to the Pandya style of architecture. Thrithala is noted for its monuments and historic ruins. The Siva temple and the ruins of a mud fort near Thrithala on the Chalissery road are notable cultural monuments.
The Paakkanaar memorial, honouring the Pariah saint, stands near Thrithala-Koottanad road. This is also the native place of renowned writer and social reformer, V. T. Bhattathiripad.
